Step-by-step explanation:

Step 1: Define

f(x) = 3x² + 2x

g(x) = 5x - 1

(f + g)(x) is f(x) + g(x)

Step 2: Find

1. Substitute in functions:                                                                                    (f + g)(x) = 3x² + 2x + 5x - 1
2. Combine like terms:                                                                                         (f + g)(x) = 3x² + 7x - 1
